The plot twist? Somewhere in the past, Jasper was kinda cool with the infected. then he got his crew at set sail for island douche

Jasper just got this crew so it seems he always been a douche. He might turn it up a bit know he is the captain of the douche squad (hey, new name for those guys) but it seem being a dick is how he copes with everything much like Sammy being ...well... Sammy.

Jasper continues to be my most favorite, misunderstood character. Everyone seems to be under the impression he's a total twat. He's just a smartass. Everyone in the comic needs thicker skin. He might step on toes, but I don't recall him ever doing anything truly fucked up to warrant any real hostility. Not to mention, when it counts, he gets the job done on a professional level.
